USB-C Power Delivery PD Plugtop & Desktop Power

USB-C Power Delivery Power Supplies

We are all familiar with USB ports on our devices and our chargers.  They have been with us for a long time now.  The days of D-type RS-232 serial data connection on consumer products are long gone.  Over the years though, USB has seen many iterations of the end termination, including the USB-A, micro, mini and USB-B connectors.  At the same time Apple have gone their own way with the reversible “Lightning” connector.

There is however a new kid on the block in USB-C, which is becoming increasingly popular with the latest Android devices and even some of the newest macbooks.  USB-C comes with no polarisation, so can be connected either way around.  It is small enough to work with handheld devices and still supports high data transfer and sufficient power to run larger devices.

Enough about data transfer, we are a power supply company after all.  One of the key features of USB-C is that it supports a new power standard known as “Power Delivery” or PD.  PD is a universal standard whereby a conversation is established between 2 connected devices to establish the voltage and power requirements needed by the device from the power supply.  In theory you can connect any PD compliant product to your equipment and it will work.

PD power devices can typically output any one of 4 output voltages.  Units start at 5V but also support 9V, 15V or 20V outputs depending on the requirements of the connected load. 

Does this mean the end of the power supply graveyard drawer?  I’m sure we all have one?  All those legacy devices, each of which required its own power supply!  There were so many choices when defining a power supply. It could be either an ac or dc output, different output voltages (5V, 12V, 15V, 24V or even 48V), different power levels and then the vast array of different connectors, polarities and locking systems.  For us at Relec, as a distributor of plugtop and desktop power supplies, it was never easy stocking what you thought customers might want.

USB-C PD is designed to bring all of that to an end.  Whilst we can still offer products with power ranges (from 30 to 60 Watts), and in plugtop or desktop configurations, the principal is clear, that these units are designed to be a one size fits all solution for multiple devices.
